Suppose that you have a reflection diffraction grating with n= = 120 lines per millimeter. Light from a sodium lamp passes through the grating and is diffracted onto a distant screen.
Two visible lines in the sodium spectrum have wavelengths 498 nm and 569 nm. What is the angular separation A0 of the first maxima of these spectral lines generated by this diffraction grating? Express your answer in degrees to two significant figures. ▸ View Available Hint(s) Δθ = Submit 15. ΑΣΦ → Dod ?
How wide does this grating need to be to allow you to resolve the two lines 589.00 and 589.59 nanometers, which are a well known pair of lines for sodium, in the second order (m2)? Express your answer in millimeters to two significant figures. ▸ View Available Hint(s) [5] ΑΣΦΑ DISC ? mm.
